STEAM-CONDENSER.

$PEC1FICATION forming part of Letters latent No. 745,186, dated November 24, 1903.

Application filed July 24, 1902. Serial No. 116'763. (N0 model) To all whom it may concern.

Be it known that I, RAYMOND H. HORN- BROOK, a subject of the King of Great Britain, residing at Canton, county of Stark, and State of Ohio, have invented a new and useful Steam-Condenser, of which the following is a specification.

My invention relates to an apparatus for condensingsteam by passing it through relatively small tubes and cooling the same by currents of air passing around and among the tubes, which process is made the subject of another application for patent; and the object of this invention is to accomplish the condensation by a natural draft caused by the movement of the condenser through the air, as when used on a locomotive or other moving object. I attain this object by the apparatus illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the condenser on the cab-roof of a locomotive, showing some parts in section; Fig. 2, a plan view of the same; Fi 3, a rear end View of the same with part of the receiving'chamber broken away; Fig. 4:, a cross-section of a corrugated tube, and Fig. 5 a longitudinal section of a crimped tube.

The tubes 1 are preferably made quite thin and of a metal which conducts heat readily, and at either end of the tubes are the plates 2, into which the tubes are securely fastened so there is no leakage of any sort. To the tube-plate at one end, preferably the forward end, is securely connected by bolts or otherwise the head 3, forming the steam-chamber 4, to which is joined the steam-pipe 5, and to the tube-plate at the other end is similarly connected the head 6, forming the receivingchamber 7, to which is joined the drainpipe 8.

WVhen used on a locomotive of the American type, the condenser is preferably located on the roof 9 of the cab 10, where it is securely attached by any convenient means, with the tubes running lengthwise of the locomotive and the lower ones freely above the cab-roof. At intervals along the tubes are the initial deflectors 11, which, as illustrated, are made of cross-plates having apertures 12 for the respective tubes,- the lower edges of which plates are freely above the cab-roof, and the upper parts thereof are bent to incline forward and extend well above the upper edge of the tube-plate and head at the forward end of the condenser. Between respective initial deflectors are located secondary deflectors, one being shown at 13, which, as illustrated, is a cross-plate having apertures 14 for the respective tubes, the upper edge of which plate is near above the upper tubes, and the lower edge is joined to the cabroof. Steam-exhaust from the cylinders, a feed water-heater, or other part of the locomotive passes into the steam chamber through the steam-pipe, from which chamber it is distributed through the respective tubes, wherein it is condensed, whence the water or vapor accumulates in the receiving-chamber and passes off through the drain-pipe to an airpump, a vacuum-pump, or other receptacle. When the locomotive is moving forward, the air first strikes the broad side of the steam-chamber, and that part which passes over it is caught by the upper inclined part of the first initial deflector, which acts as a scoop and turns the air in a strong current diagonally downward around and among and impinging the respective tubes, and thence backward below the initial deflector, some of the air-current escaping at the sides and the remainder of it striking the secondary deflector, which turns it upward around and among and impinging the respective tubes and over said secondary deflector. The next initial deflector in a similar manner catches more air and turns it in a strong current diagonally downward around and among and impinging therespective tubes, as before,which air-current finally strikes the flat side of the receiving-chamber and escapes above and to the sides of the same. The air-currents are indicated in a general Way by arrows in Fig. 1. By thus passing strong currents of fresh and relatively cool air at intervals along the condenser to and fro around and among and impinging the respective tubes the same are constantly kept quite cool and the condensation is quickly accomplished.

While the deflectors as illustrated are made of plates straight across the condenser, any suitable forms or shapes of straight or curved deflectors can be used which will catch the air as a scoop and carry it in a current to and fro around and among and impinging the respective tubes Without changing the character of my invention, and instead of locating the respective tubes in rows opposite each other as shown in Figs. 1 and 2, the tubes can be so disposed that each tube in one row is opposite the space between tubes in the adjacent row, as shown in Fig. 3, thus exposing each individual tube more fully to the cooling medium, and to increase the surface of the tubes they can be longitudinally corrugated, as shown in Fig. 4, or crimped, as shown in Fig. 5.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of a locomotive; a steam-chamber joined to a steampipe, a receiving-chamber joined to a drain-pipe, and

relatively small tubes connecting said chambers,on saidlocomotive; and initialdeilectors, and secondary deflectors adapted to guide aircurrents downward and then upward, respectively, around and among said tubes, said deflectors being located altcrn ately at intervals along said tubes, and there being apertures in the respective deflectors for the tubes.

2. The combination of a locomotive; a steam-chamber joined to a steam-pipe, a receiving-chamber joined to a drain-pipe, and relatively small longitudinal tubes connecting said chambers, on said locomotive; and transverse deflectors on said tubes arranged to guide air-currents around and among the tubes to impinge the same.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
